1. which kind of function best models the set of data points (-1, 22), (0,6), (1,-10), (2,-26),
and (3, 42)
(1 poin
linear
quadratic
exponential
none of the above

You can clearly check, by plotting them, that the points don't lie on a line.

Moreover, they present a descending pattern, until the last point, which comes back up.

This kind of behaviour (descendent and then ascendant) can be modelled by quadratic functions (parabolas)

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.
